Robert Pattinson had to learn how to run for new Twilight movie Eclipse.

The hunky British actor — who plays vampire Edward Cullen in the sexy film franchise — told the UK’s Reveal magazine that he had to hit the treadmill in preparation for the saga’s third installment.

“I had to learn how to run properly. In the last two films, I ran in a limp/skip,” he said.

“I had to run more solidly this time so I spent a lot of time on a giant treadmill. It was like one of those things that mice run around in.”

Rob, 24, recently admitted he was “confused” as a teenager.

“I don’t think I was that angry as a teenager, although I will confess to being confused and frustrated. I suppose I could be a bit of a pain at times,” he said.

“I think it takes time to find one’s identity and define one’s ambitions in life. Then you grow bored with being disillusioned and alienated and now I’m trying to enjoy things more. It’s less stressful! You don’t have to change the world to be happy.”
